Prepare to feel old. In 1993, I was 5. I went to an English store in Stuttgart this summer and, turns out, they had a very large selection of Scotch. Even better, he sold it either by the bottle, or in little 4 oz sample bottles. I got my brother a little bottle from his birth year. I tried to find mine, but most of his scotch was away at a festival, so I had to settle for one from '89. I don't know what your position is on him drinking a little scotch at 18, but maybe keep it in mind for 21.
